CHITONOMYCES AND RICKIA. 15 



Chitonomyces inflatus nov. sp. 



Form rather stout ; hyaline, becoming very faintly yellowish. Basal 

 cell suffused with blackish brown, deeper below, conspicuously in- 

 flated above; cell b small, somewhat broader than long, but forming 

 an abrupt constriction between cell a and the cells above, usually 

 slightly distorted from the fact that the receptacle is often more or 

 less geniculate in this region; cell b followed by two relatively large 

 cells, apparently cells d and c, which are subequal, broader, and dis- 

 tinguished by a slight indentation above; a third cell, apparently cell 

 c, small, subtriangular, lying somewhat obliquely above them is 

 visible only on the left side; cell / relatively short, ending in the 

 insertion of the secondary appendage, the appendiculate cell h not 

 being separated from it; cell h overlapping cell / for about half its 

 total length; cell i normally longer than broad, tapering slightly to its 

 nearly symmetrical rounded tip. Perithecium relatively large and 

 stout, curved outward distally, its upper half free; the tip slightly 

 distinguished and bent outward; the apex hardly distinguished, 

 rather narrow, blunt, subsymmetrical; one or more of the lip-cells 

 slightly prominent. Spores about 40X2.5 ^t. Perithecium 75X25 /x. 

 Total length to tip of perithecium 100-120 X 26-30 fx. 



On the anterior legs of a small dark dityscid. Manila, P. I. (Banks), 

 No. 2409. 



A species readily distinguished by its large inflated and suffused 

 basal, and its constricted subbasal cells. It corresponds to C. Bides- 

 sarius and a few species among those which inhabit hosts other than 

 Laccophili, from the fact that no appendiculate cell h is separated 

 from cell /. The identity of cells c and (/ is also obscure, it being un- 

 certain whether the small cell mentioned in the description, which 

 lies above and partly overlaps the other two, should be regarded as 

 cell c or cell d. 



ChitonomyGes excavatus nov. sp. 



Wholly hyaline. Basal cell rather short and stout, not twice as 

 long as broad : cell b flattened, horizontal ; cells d and e similar, greatly 

 elongated, becoming slightly broader distally; cell e slightly longer, 

 cell d surmounted by cell c, which is relatively small and subtriangular; 

 cell h not separated from cell /, which thus tapers to its appendiculate 

 point, and is about half overlapped by cell g, its whole length being 

 about equal to that of cell e; cell g rather strongly convex externally
